Non-aerated solid tyre with damping device

Abstract

The invention relates to a non-pneumatic solid tyre with a plurality of damping devices, which belongs to a tyre structure, in particular to a solid tyre used on electric bicycle, automobile and other vehicles. The invention comprises an outer steel ring and an inner steel ring with a coaxial line; a rubber band coating on the outer flank of the outer steel ring; a plurality of damping devices are provided between the outer steel ring and the inner steel ring uniformly. Both ends of the damping devices are connected to the outer and inner steel rings respectively with bolt and nut; a damping spring and two homopolar magnets are provided inside the damping devices; the repellant force produced by the two homopolar magnets enable the damping devices to stretch and compress, having the damping function. The invention can replace the prior pneumatic tyre in the automobile and the electric bicycle, and has the advantages of efficient damping, high stability and good conformability, no blow-out and deformation under long time press and other excellences. The solid tyre can avoid the worries of the user about tyre replacement after blow-out and the short service life.

Description

technical field [0001] The invention relates to a tire structure, in particular to an air-free solid tire structure with a shock absorbing device which can be used on vehicles such as electric bicycles and automobiles. Background technique [0002] The land vehicle such as electric bicycle, automobile generally uses wheel, and the tire widely used at present all is to comprise the structure of cover tire and pneumatic inner tube, and pneumatic inner tube plays shock-absorbing effect. However, there are many problems in this type of tire. For example, the service life is short, and the inner and outer tubes need to be replaced after a period of time, which increases the cost of use; the inner tube must be repeatedly inflated, and it is easy to be poked by some sharp objects such as nails on the road. Broken inner tube causes air leakage and cannot travel, and because the electric vehicle is heavier, it will become very difficult to implement at this time, which brings trouble...

AI Technical Summary

Problems solved by technology

However, there are many problems in this type of tire. For example, the service life is short, and the inner and outer tires need to be replaced after a period of time, which increases the cost of use; the inner tire must be repeatedly inflated, and it is easy to be poked by some sharp objects such as nails on the road. A broken inner tube will cause air leakage and make it impossible to drive, and because the electric car is heavy, it will be very difficult to implement at this time, which will bring trouble to people and waste a lot of time and money on car repair

[0003] Solid tires are the replacement products of pneumatic tires, without the disadvantages of puncture and repeated inflation. However, due to their relatively poor shock absorption performance, they are generally used in occasions with slow speed and high load, and are not widely used in electric bicycles, automobiles and other fields.
